Are you getting any errors.. what does evo scan show at the bottom right, does it say connection successful or something else?

 

It will say connection unsuccessful, could not connect to com port 2 and that is it. It will always connect to comport 5 but will not get the a/f reading, and when i change it to com port 5 it will connect but not give me an a/f reading. Wierd stuff.

 

Im actually having the same problems as you with my windows vista. Everything works fine as for datalogging other than the wideband with my LM-1 unit.
